Took me slightly less than a week. First 3 days was almost nil that I had to supplement with formula and let my baby latch as and when needed. It was tough but pump 8 sessions a day ~20mins each session until you establish a stable supply. Do not miss overnight sessions as 1-5am is when prolactin hormone is the highest and give you the most yield. If you’re really desperate; do one power pump session during one of the overnight sessions (20min pump, 10min rest, 10min pump, 10min rest, 10min pump - total 1 hour session). Stop power pump once your supply is up cos it might cause oversupply which is another problem by itself! My baby is now 2W old and I’ve got a stable milk supply without needing to supplement formula (: good luck in your BF journey
power pump everyday atleast once , eat well and drink lots of fluids. try to clam yourself before each pump so your let down is good.
wasnt successful personally
